for that is free which is its own cause. In the word debt, therefore, is implied a certain exigence or necessity of the thing to which it is directed. Now a twofold order has to be considered in things: the one, whereby one created thing is directed to another, as the parts of the whole, accident to substance, and all things whatsoever to their end; the other, whereby all created things are ordered to God. Thus in the divine operations debt may be regarded in two ways, as due either to God, or to creatures, and in either way God pays what is due. It is due to God that there should be fulfilled in creatures what His will and wisdom require, and what manifests His goodness. In this respect, God's justice regards what befits Him; inasmuch as He renders to Himself what is due to Himself. It is also due to a created thing that it should possess what is ordered to it; thus it is due to man to have hands, and that other animals should serve him. Thus also God exercises justice, when He gives to each thing what is due to it by its nature and condition. This debt however is derived from the former; since what is due to each thing is due to it as ordered to it according to the divine wisdom. And although God in this way pays each thing its due, yet He Himself is not the debtor, since He is not directed to other things, but rather other things to Him. Justice, therefore, in God is sometimes spoken of as the fitting accompaniment of His goodness; sometimes as the reward of merit. Anselm touches on either view where he says (Prosolog. 10): "When Thou dost punish the wicked, it is just, since it agrees with their deserts; and when Thou dost spare the wicked, it is also just; since it befits Thy goodness."
Reply to Objection 4: Although justice regards act, this does not prevent its being the essence of God; since even that which is of the essence of a thing may be the principle of action. But good does not always regard act; since a thing is called good not merely with respect to act, but also as regards perfection in its essence. For this reason it is said (De Hebdom.) that the good is related to the just, as the general to the special.
Whether the justice of God is truth?
Objection 1: It seems that the justice of God is not truth. For justice resides in the will; since, as Anselm says (Dial. Verit. 13), it is a rectitude of the will, whereas truth resides in the intellect, as the Philosopher says (Metaph. vi; Ethic. vi, 2,6). Therefore justice does not appertain to truth.
Objection 2: Further, according to the Philosopher (Ethic. iv, 7), truth is a virtue distinct from justice. Truth therefore does not appertain to the idea of justice.
On the contrary, it is said (Ps. 84:11): "Mercy and truth have met each other": where truth stands for justice.
I answer that, Truth consists in the equation of mind and thing, as said above ( Question [16], Article [1]). Now the mind, that is the cause of the thing, is related to it as its rule and measure; whereas the converse is the case with the mind that receives its knowledge from things. When therefore things are the measure and rule of the mind, truth consists in the equation of the mind to the thing, as happens in ourselves. For according as a thing is, or is not, our thoughts or our words about it are true or false. But when the mind is the rule or measure of things, truth consists in the equation of the thing to the mind; just as the work of an artist is said to be true, when it is in accordance with his art.
Now as works of art are related to art, so are works of justice related to the law with which they accord. Therefore God's justice, which establishes things in the order conformable to the rule of His wisdom, which is the law of His justice, is suitably called truth. Thus we also in human affairs speak of the truth of justice.
Reply to Objection 1: Justice, as to the law that governs, resides in the reason or intellect; but as to the command whereby our actions are governed according to the law, it resides in the will.
Reply to Objection 2: The truth of which the Philosopher is speaking in this passage, is that virtue whereby a man shows himself in word and deed such as he really is. Thus it consists in the conformity of the sign with the thing signified; and not in that of the effect with its cause and rule: as has been said regarding the truth of justice.
Whether mercy can be attributed to God?
Objection 1: It seems that mercy cannot be attributed to God. For mercy is a kind of sorrow, as Damascene says (De Fide Orth. ii, 14). But there is no sorrow in God; and therefore there is no mercy in Him.
Objection 2: Further, mercy is a relaxation of justice. But God cannot remit what appertains to His justice. For it is said (2 Tim. 2:13): "If we believe not, He continueth faithful: He cannot deny Himself." But He would deny Himself, as a gloss says, if He should deny His words. Therefore mercy is not becoming to God.
On the contrary, it is said (Ps. 110:4): "He is a merciful and gracious Lord."
I answer that, Mercy is especially to be attributed to God, as seen in its effect, but not as an affection of passion. In proof of which it must be considered that a person is said to be merciful [misericors], as being, so to speak, sorrowful at heart [miserum cor]; being affected with sorrow at the misery of another as though it were his own. Hence it follows that he endeavors to dispel the misery of this other, as if it were his; and this is the effect of mercy. To sorrow, therefore, over the misery of others belongs not to God; but it does most properly belong to Him to dispel that misery, whatever be the defect we call by that name. Now defects are not removed, except by the perfection of some kind of goodness; and the primary source of goodness is God, as shown above ( Question [6], Article [4]). It must, however, be considered that to bestow perfections appertains not only to the divine goodness, but also to His justice, liberality, and mercy; yet under different aspects. The communicating of perfections, absolutely considered, appertains to goodness, as shown above ( Question [6], Articles [1],4); in so far as perfections are given to things in proportion, the bestowal of them belongs to justice, as has been already said ( Article [1]); in so far as God does not bestow them for His own use, but only on account of His goodness, it belongs to liberality; in so far as perfections given to things by God expel defects, it belongs to mercy.
Reply to Objection 1: This argument is based on mercy, regarded as an affection of passion.
Reply to Objection 2: God acts mercifully, not indeed by going against His justice, but by doing something more than justice; thus a man who pays another two hundred pieces of money, though owing him only one hundred, does nothing against justice, but acts liberally or mercifully. The case is the same with one who pardons an offence committed against him, for in remitting it he may be said to bestow a gift. Hence the Apostle calls remission a forgiving: "Forgive one another, as Christ has forgiven you" (Eph. 4:32). Hence it is clear that mercy does not destroy justice, but in a sense is the fulness thereof. And thus it is said: "Mercy exalteth itself above judgement" (James 2:13).
Whether in every work of God there are mercy and justice?
Objection 1: It seems that not in every work of God are mercy
